Florida Panthers backup goalie Scott Clemmensen underwent arthroscopic knee surgery last week and will be sidelined for three weeks.

Panthers GM Dale Tallon said he’ll be in the market for a veteran backup for the pre-season.

Free agent options include Tim Thomas, Rick DiPietro, Ilya Bryzgalov, Johan Hedberg and former Panthers starter Jose Theodore.

TSN’s Bob McKenzie reported the Panthers extended a professional tryout offer (PTO) to Thomas. His agent, Markus Lehto, said he’s had discussions with several teams, but added his client wants to be a starting goaltender. The Panthers have already pencilled in Jacob Markstrom for that role.

The Panthers also extended a PTO to Theodore, which he declined, as he’s awaiting a contract.
