Tuukka Rask gave up two goals in the third period and was then beaten by both shootout tries as the Bruins fell to 1-1-1 - 0-1-1 against Florida. The Panthers are 2-1 in the preseason.
Seguin, the No. 2 pick in the June draft, and the newly acquired Nathan Horton scored second-period goals to give the Bruins a 2-0 lead entering the third. But Radek Dvorak and Kenndal McArdle scored in the first 8:46 of the third period to tie it, with Marty Reasoner assisting on both goals.
