GIANT striker Stefan Maierhofer trained with Millwall on Thursday.
The 6ft8in former Austrian international, who has been without a club since leaving German side FC Köln last summer, took part in the Lions' first session since defeat to Blackpool.
Boss Ian Holloway wants to sign a tall targetman before this weekend's local derby against Charlton, with Steve Morison a doubt for the game with a neck injury.
And 31-year-old Maierhofer could fit the bill, although it is unclear whether a deal is likely.
The ex-Bayern Munich youngster has not played a competitive fixture since the end of last season, so Holloway may be concerned about his lack of match fitness.
Maierhofer played in the Premier League for Wolves in the 2009-10 season after a £1.8m-move from Rapid Vienna, but he left Molineux the following year.
