AIDEN O'Brien is set to return to full training with Millwall next week.
O'Brien has been out since picking up an ankle ligament injury in the 4-3 win at Leeds on January 20.
The 24-yer-old attacker has scored six goals this season, including four in three games before his spell on the sidelines.
He was snapped at Millwall's training ground this week during running drills with Byron Webster, who has progressed to doing ball work as he aims to return from a crucial ligament injury before the end of the season.
Lions boss Neil Harris said: "Aiden is running now outside with the sports scientist. Him and Byron are working together and going really well.
"We'll hopefully have Aiden back in training towards the end of next week."
Millwall face Sunderland this weekend as they bid to stretch their unbeaten league run to nine games.
Jordan Archer's mistake earlier this season allowed Sunderland claim a 2-2 draw, but he has kept four clean sheets in his last six games to earn praise from his manager.
"He's played a lot of games for young man. Goalkeepers, in particular, are looking at 2-300 games before becoming established," Harris said.
"Jordan's confidence is high and he has confidence in the ability of the players in front of him.
"Thirteen clean sheets this year is a great return. At the start of the season I thought that if we got to 15 then that would go a long way to helping us stay in the division. We have 13 already with 12 games to go so the hope is we get to 15 as quickly as we can and go from there."
