The Panthers will open their training camp on Thursday morning at Iceplex and on Tuesday they released their 59-man roster. The big question is whether or not veteran free-agent goalie Tim Thomas will be in one of the nets at Iceplex Thursday morning at 9 a.m. The twitter universe was abuzz with reports that the Panthers offered Thomas a PTO (professional tryout) and it certainly makes sense as GM Dale Tallon told us Sunday that he was shopping for a veteran netminder once Scott Clemmensen went down with a knee injury. I called Thomas’ new agent Markus Lehto and I’m awaiting a call back for confirmation. The Panthers wouldn’t confirm the Thomas invitation which according to tweets by and TSN’s Bob McKenzie the 39-year-old two-time Vezina Trophy winner hasn’t decided which team to accept PTO’s with yet. It’s possible the Islanders and Canucks are interested but Thomas who was MVP in the 2010-11 season when he led the Bruins to a Stanley Cup still wants to be a starter and not a backup. Clemmensen is expected back for the season opener but he’s 36 and coming off one of the worst seasons of his 10-year career. The big Swede Jacob Markstrom told me he’s looking at this training camp as another opportunity to earn a spot and he’s right especially because he’s still on a two-way contract and is coming off an uneven stint last season. The Panthers also invited tryout goalie Rob Madore free agent signee Michael Houser and veteran AHLer Dov Grumet-Morris. Only Markstrom has NHL experience of the aforementioned goalies. Thomas has never really been the same after his controversial decision to turn down President Obama’s invitation to the White House with the Bruins after they won the Cup. He decided to sit out last season for personal reasons involving family and his religious faith. In 2011-12 Thomas was 25-19-1 with a 2.36 GAA.
