Should Manny keep his promise - even if it means putting his friend in jeopardy?

When the Grizzlies' first baseman is sidelined two days before the playoffs, catcher Manny Griffin and second baseman Stu Fletcher take it upon themselves to help his replacement, Sean Wilson, become a better player. The three practice together and all is going well - until Sean unleashes a wild throw that hits Stu right in the head! Stu is dazed but won't let Manny call for help. In fact, he makes Manny promise not to say anything about the injury. 'I'm perfectly fine,' he insists. 'And the team needs me.'

A few days later, however, Stu starts acting funny. Manny realizes then that his friend is anything but fine. Now he faces a difficult decision: should he break his promise - or keep silent and hope that he's not putting Stu in the danger's path?
