Coach Jon Cooper said Saturday that Bishop is considered day-to-day but did not disclose whether the Vezina Trophy finalist would play Monday in Game 2.
"Everything's been really good so far with Ben," Cooper said during a conference call. "Much better news than the scene we saw when he was carted off. As for any playing status, I have no answer or no update yet."
Bishop appeared to have injured his left knee with 7:35 remaining in the first period of Tampa's 3-1 win over the Pittsburgh Penguins. After the game, Cooper said X-rays were negative and there was no structural damage.
If Bishop can't go, the Lightning will rely on Andrei Vasilevskiy, a 21-year-old who was thrust into a similar position during last spring's Stanley Cup finals against Chicago, winning Game 2 in relief. Vasilevskiy stopped 25 shots after coming in for Bishop in Game 1.
