Millwall defender Byron Webster is a major injury doubt for Sunday’s League One play-off final against Barnsley.

The 29-year-old hobbled off in the second leg of the semi-final against Bradford at the Den with a hamstring problem.

The centre-back has developed into an intergral member of the Lions’ dressing room but may miss the trip to Wembley.

Harris said: “Byron came off with a strained hamstring so it’s not ideal preparation because he has been colossal for us in recent weeks and months.

“It’s going to be tough for him for Sunday and we’ll give him every opportunity to make it.

“But if not then in Tony Craig, our club captain, and Sid Nelson, who has played really well this year, I’ve got players who can step into the position admirably.”
