PITTSBURGH — Injured Tampa Bay goalie Ben Bishop still hopes to return for the Lightning’s Eastern Conference final series against the Pittsburgh Penguins, according to a tampabay.com report.

Bishop, a former University of Maine star, injured his lower left leg in the first game of the series.

He would like to return but will not rush and risk further injury.

“It’s tough being in the position [goalies are] in, kind of the last line of defense. You don’t want to go out and play when you’re not ready,” Bishop said in the tampabay.com report. “If you were maybe a forward, you’d be okay to go out and tough through it. But as the last line of defense, you don’t want to go out there and do that to your teammates. You’ve got to wait until you’re ready to go and feel like you can help the team win.”

Bishop added that he doesn’t need to be 100 percent to play but needs to feel comfortable doing certain movements, up and down, side to side.

Bishop’s backup, Andrei Vasilevskiy, helped the Lightning edge the Penguins in overtime, 4-3 Sunday night in Pittsburgh, and take a 3-2 series lead.

In overtime, Tyler Johnson deflected Jason Garrison’s wrist shot from the left circle into the net only 53 seconds into overtime to give the Lightning the victory.

Nikita Kucherov led a comeback from a two-goal deficit with two goals as the Lightning won for the second time in the three games in Pittsburgh. They won’t have to return there if they can win Game 6 Tuesday in Tampa, where teams split Games 3-4.

The Lighting are one win away from the Stanley Cup finals for the second straight season.

The Penguins gambled by returning goalie Marc-Andre Fleury to the net for the first time in 51 days, benching rookie Matt Murray, but Fleury was outplayed by rookie Vasilevskiy, who made 31 saves to Fleury’s 23. Fleury now is 1-8 in his last nine playoff starts.

One constant on every Tampa Bay goal: Penguins star defenseman Kris Letang, playing without usual partner Trevor Daley, was on the ice. Daley will miss the rest of the playoffs with a broken left ankle that occurred in Game 4.

Olli Maatta, back after being benched for three games for uneven play, figured on two of the Penguins’ first three goals — exactly what coach Mike Sullivan wanted upon returning him to the lineup.

But, again, the Penguins’ big names, Sidney Crosby and Evgeni Malkin, couldn’t produce a goal in a Game 5 that, based on prior NHL results of series tied at 2, sends the winner on to the next round about 75 percent of the time.

The Penguins led 3-2 late in the third, but Kucherov scored his second of the game — and 11th of the playoffs — at 16:44. Johnson’s shot from the left point deflected to Kucherov behind the net, and he easily beat Fleury on a wraparound.

The Penguins took their 3-2 lead by scoring in the final minute of each of the first two periods — literally the final second of the first period — with left winger Chris Kunitz involved in both goals.

After the Lightning rallied from a two-goal deficit to tie it at 2-2 on goals 1:10 apart in the second by Alex Killorn and Kucherov, the Penguins regained the lead when Kunitz punched the puck past Vasilevskiy with 50 seconds left in the period.

Maatta swiftly carried the puck beyond the goal line, then fed it to the high slot to Malkin, who put it on net. Just as Vasilevskiy seemed ready to grab it, Kunitz nudged it into the net for his fourth of the playoffs and third of the series.

Previously, after holding the Lightning to four shots in the first period, the Penguins scored the game’s first goal with only seven-tenths of a second left. Kunitz, while falling down, shoved the puck up-ice to Bryan Rust, who beat defenseman Victor Hedman for a shot that rebounded to defenseman Brian Dumoulin, who put it inside the far post.
