NEIL Harris is weighing up his attacking options this weekend if a stomach muscle tear keeps Steve Morison out for a second successive game.
Harris paired Lee Gregory and Aiden O'Brien up front together in the 1-0 defeat to Brentford last Saturday, with Tom Elliott and Fred Onyedinma coming on in the second half as Millwall chased the deficit.
Elliott had missed the previous six games with a thigh injury, but he could start his first league game for the club against Birmingham.
"It was a gamble putting Tom on when we did," Harris admitted. "But needs must and I felt we needed something different.
"The plan was to give him 20 or 30 minutes after he'd been out for over five weeks.
"His size and his stature makes him a different animal to everyone else, we have to be careful with him. Certainly, the nature of the injury, a thigh strain, you have to be really careful.
"I was pleased that we got him on the pitch in the end for about 35 minutes including added-time.
"That was a bonus and he was a little bit rusty, but he has worked hard during his recovery to push himself. He couldn't have started that game, he might have made 45, 50 minutes at the most.
"He certainly comes into the thinking for this weekend. The question will be how long can he play.
"Fred played extremely well up there for three games, but it's just whether he and Lee Gregory is a good combination.
"It was a difficult one for Aiden to go back playing up front at the weekend for the first time since last season, given the way Brentford play.
"He did a god job but looked a lot more comfortable when he moved back to a wide area.
"Birmingham will be slightly different, a bit more up-and-at-em, a bit more Millwall-like. There are plenty of considerations for this weekend."
Shaun Williams and Byron Webster are out, but Harris should have no new injury concerns.
