Good news.
Last time (also a torn triceps), he was out for nearly a half year, I think. My bet is Summerslam.

Tthis time he tore an already surgerly repaired muscle.
I'm hoping for the best and that he doesn't rush his return with the possibility of re-injuring himself.
The only good news to this all is, that now he'll have time to nurse his back injury as well! So he'll be able to make a comeback being a 100% again!
