Jason Heyward’s concussion might end his season prematurely, a somber conclusion to the worst year of his big-league career.

Heyward hasn’t played since Sept. 11, when he exited in the fourth inning against the San Francisco Giants after being kneed in the head on a slide into second base. The play caused a concussion that landed him on the injured list.

Although the Cubs have discussed shutting him down, Heyward wants to do everything he can to come back before the season ends Oct. 3, manager David Ross said Wednesday.

Heyward, 32, went through exertion tests Tuesday and came out OK; he was expected to do them again sometime Wednesday.

“In my mind, talking to him and starting to count down days of trying to get back, the word I’d probably use is ‘doubtful,’ but we’re definitely holding out hope,” Ross said before the Cubs’ 5-4 loss in the series finale against the Minnesota Twins. “It’s just such a tricky injury.”
