Alex McLeish has confirmed that Jermaine Jenas is likely to have to wait a further two weeks before he could make his Aston Villa debut.
The midfielder, who is on a season-long loan at the club from Tottenham, missed the thrilling 2-2 draw against Everton on Saturday after getting injured in training before even kicking a ball competitively.
Jenas, 28, wrecked his chances of making his debut at Goodison Park after pulling up in training with a thigh strain on Friday.
And McLeish revealed his injury was as a result of his over-exuberance on the Bodymoor Heath training pitches.
"He got a kicking strain and there was no way we were risking him," McLeish told the Sunday Mercury. "I think he was a bit over-zealous. He really pushed himself in training.
"He may have even felt it a couple of days ago but decided to come and train such was his keenness to be involved.
"You can't knock a player for that. I hope it doesn't set him back too long and he'll be back with us within a couple of weeks because we need that competition in the centre."
The Villa boss also confirmed the club's medical staff will check on the hamstring injury suffered by striker Emile Heskey during the first half of the clash on Merseyside.
"I don't know how serious again, but it will be scanned on Monday," added McLeish. "It's disappointing because he's been involved in every game.
"He's been really strong and unbelievably you have a two-week break and you think the fatigue would be gone and the players would have recovered and he does his 'hammy', but that happens in football."
