Ellerby sustained a lower-body injury in the second period of Thursday's 4-0 loss at New Jersey in Game 4 when he was checked by Devils center Stephen Gionta into the Devils bench where the open door meets the stanchion. Ellerby was making his first appearance since March 15.
Ellerby was in the lineup because Garrison was a late scratch because of a lower-body injury. Dineen said the Panthers were "cautiously optimistic" Garrison would be able to play Saturday.
Dineen said the Panthers might call up a defenseman from the AHL's San Antonio Rampage, with the most likely candidate being Tyson Strachan.
After being through it and seeing the other [outdoor] games on TV, just the atmosphere is spectacular. To stand here -- and we are essentially almost on the blue line -- and look up [into the stands] and knowing it is going to be packed and playing our biggest rival in this setting is going to be pretty special.
