KANSAS CITY -- Royals second baseman Miguel Tejada left Saturday night's 5-3 loss in the seventh inning with tightness in his right calf after diving for a single by Red Sox left fielder Mike Carp.
"When he dove for that ball, his right calf got real, real tight so we're evaluating it," manager Ned Yost said.
Tejada sat up and tried to stretch out his leg before Yost and trainers came out to check on him. He walked off under his own power and was replaced by Elliot Johnson. Tejada was wearing a compression sleeve on his calf after the game.
"They are going to wait till tomorrow to evaluate me and see what's going on," Tejada said. "Right now, I'm feeling it pull."
Tejada was 1-for-3, including an RBI single in a three-run fifth before leaving the game. He was batting .288 overall and .305 (18-for-59) since the All-Star break.
Joseph, Smith up from Omaha; Bueno DFA'd
KANSAS CITY -- With right-hander Wade Davis set to return from family emergency leave on Sunday, the Royals are expecting one of their Saturday roster moves to be very temporary.
Left-handers Donnie Joseph and Will Smith were recalled from Triple-A Omaha, though one of them will likely return to Omaha when Davis returns. Left-handed reliever Francisley Bueno was designated for assignment and outfielder Lorenzo Cain was placed on the 15-day disabled list with an oblique strain.
Bueno pitched in just one game since being called up from Omaha on Thursday. In Friday night's 9-6 win over the Red Sox, he contributed 2 1/3 scoreless innings and got the victory.
"Bueno went 2 1/3 innings, so we brought Donnie up to give us that protection short and Will long because [the Red Sox are] a pretty good left-handed matchup team," manager Ned Yost said.
Joseph is up for the second time this season. He made his Major League debut on July 11 at Yankee Stadium and retired Vernon Wells before giving up a walk and a single. He pitched a scoreless inning the next day at Cleveland and was optioned back to Omaha. For Omaha, Joseph is 3-3 with a 3.42 ERA in 41 games with 77 strikeouts in 50 innings.
"I've wanted to play [at Kauffman Stadium] pretty bad," Joseph said. "I'm excited to be here finally. I just hope I can go in there and do my job like everyone else in this clubhouse has been doing. This team is on fire right now and everything is going great."
This is Smith's fifth move onto the Kansas City roster this season. He's previously pitched in seven games, including one start, going 1-1 with 3.26 ERA. For Omaha, he's 6-3 with a 3.03 ERA in 26 games (10 starts).
"Any way you can get up back up to the big leagues, it doesn't matter how many times," Smith said. "It's better than the Minors. You're happy to be there and see everybody."
Davis will return to the rotation after missing one start and pitch for the Royals on Monday following the death of his stepbrother.
"He's been working and been throwing," Yost said. "He's ready. He's in a pretty good frame of mind."
Yost: Salvy great chance to return Sunday
KANSAS CITY -- Royals catcher Salvador Perez likely will be reinstated from the seven-day disabled list on Sunday. Perez was diagnosed with a low-grade concussion which he sustained last Saturday in New York.
"With Salvy there is a great chance he will come off tomorrow," manager Ned Yost said. "We don't know, we're keeping our fingers crossed that all the paperwork gets back."
In his absence, George Kottaras and Brett Hayes, who was recalled from Triple-A Omaha when Perez hit the DL, have been splitting time behind the plate.
Paulino on track with his rehab schedule
KANSAS CITY -- Right-hander Felipe Paulino was back in the Royals' clubhouse on Saturday for some additional work with trainers following his Thursday rehab start with Triple-A Omaha.
"He's doing great," manager Ned Yost said. "I look at the reports and the reports were all positive. Good velocity, throwing the ball fine. That's a natural case. They'll go down, throw their rehab and come back with the trainers who will monitor and work on them. He's upbeat, he feels good, he's moving right along."
Paulino, who is recovering from Tommy John surgery performed in July 2012, allowed four runs (two earned) on five hits and a walk with four strikeouts in Omaha's 6-4 loss to Sacramento. He threw 62 pitches -- 46 strikes.
"I've been feeling pretty good," Paulino said. "I liked how I woke up yesterday and I feel a lot better today. I am throwing a bullpen today just to prepare for my next start by Tuesday."
Paulino began his rehab assignment on June 11, but was sidetracked by lower back and shoulder stiffness.
"I've been fighting for this the last couple months," Paulino said. "Now, it's just following my schedule and trying to keep my dates, and hopefully I will be back soon."
