"It was more muscle-related, in terms of soreness, rather than a pull," manager Buddy Bell said. "Hopefully that is the case."
DeJesus was playing in just his second game after missing six games over the initial pull.
While both DeJesus and Bell don't anticipate missing a lot of time with the latest setback, neither wouldn't rule out a trip to the disabled list.
"I've played only two games healthy so far this year," DeJesus said. "You can't rush these things. It's one of those you've got to see how it feels."
"[A stint on the DL] is always a possibility right now," Bell said. I don't think that's the case, especially if it's muscle soreness."
DeJesus is also dealing with overcoming the mental hurdle associated with a nagging ailment.
"There were two balls in the gaps I feel I could've caught, but where I was I couldn't get into that extra gear," DeJesus said. "It's one of those things that, yeah, it's in your head. You have to get to the point where it's out of your head, and right now, it's not."
Hernandez close? Runelvys Hernandez makes another start for Omaha on Wednesday night at Nashville, and Bell said the starter will be back in Kansas City as soon as he shows he's ready.
"It's up to him," Bell said. "He's basically going to determine whether he comes up here depending on how he throws.
"The guy's been in the big leagues for three years, so we don't expect him to go down there and strike everybody out. I'm looking for stuff, maintaining his stuff. His velocity was up last time and that's important to me, in terms of his arm being as quick as it needs to be."
Hernandez has an ERA of 11.00 over two starts, while giving up 14 hits and seven walks over nine innings. But he did get the win in his last start against Memphis on April 14, surrendering three runs and seven hits over six innings.
More aches and pains: Another day, another patchwork lineup for the Royals. Joining the ranks of the walking wounded is second baseman Mark Grudzielanek, who, according to Bell, "has some achilles issues."
Tony Graffanino got the start in Grudzielanek's place.
Reggie Sanders was also out of the lineup on Wednesday, but it's not an injury-related move. He's taking his usual break with the day game following a night game.
Coming up: The Royals head back to Kauffman Stadium for a nine-game homestand, starting with three against the Indians on Friday.
Left-hander Mark Redman makes his second start of the season, going up against Cleveland southpaw Cliff Lee. Game time is 7:10 p.m.
