Timonen (blood clots) is tentatively targeting a return to the lineup Feb. 28 against the Rangers, Randy Miller of the Newark Star-Ledger reports.Timonen resumed his rehab activity last Friday and will require a couple more weeks of working out to get back to full strength after being sidelined since August with the blood clots. The Flyers will see how Timonen progresses in his subsequent sessions over the next several days before a return date will be more accurately pinpointed. If Timonen does indeed return before the end of February, it might be enough to convince playoff contenders to make a trade for the 39-year-old in what will mark his last NHL season.
