The Panthers tied the score with 5:50 gone in the third period, when Tomas Kopecky stole the puck and fed a pass to Shawn Matthias, who buried his sixth goal of the season.
After Friday's game, Dineen seemed upbeat when asked about Markstrom, who recovered from his poor start to make 25 saves.
"(Goalie coach) Robb Tallas and I will spend some time with 'Markie', and there's lots of areas (of his game) that we can talk about," Dineen said. "But at the end of the day, he gave us a pretty solid chance to win."
NOTES: With team captain Ed Jovanovski and alternate captain Stephen Weiss out with injuries, Dineen has made some changes. Forwards Kopecky and Tomas Fleischmann are now alternate captains. Defenseman Brian Campbell's status as alternate captain is unchanged. ... Entering Friday, the Panthers' starting goalie has failed to last past the second period in four of the past five games. The most recent example was on Thursday, when Markstrom was replaced after allowing two goals on the first two Capitals shots. His replacement, Scott Clemmensen, wasn't very good, either, allowing five goals the rest of the way. ... The Jets, meanwhile, feel fortunate to have Al Montoya as their backup goalie. He is 3-0 with a 2.33 goals-against average. ... Montoya played so well Thursday that a columnist for the Winnipeg called for him to start Friday against the Panthers -- to no avail. ... The Jets close their four-game road trip Sunday in New Jersey. The Jets return home Tuesday to play Toronto. ... Up next for the Panthers is a home game Sunday against Montreal.
