Looks as though Bourgeois will be back soon after all. Geoff Blum's jacked up elbow hasn't gotten any better over the last 36 hours.
Blum:
"Even brushing my teeth hurts right now. It hasn't gotten any better at all."
Mills:
"As of right now, we're waiting for the doctor to bring the MRI in, and he hasn't shown up yet. [Blum] showed up this afternoon to get treatment, and it was still swollen, and he still can't straighten it out. So we're kind of in a state of flux here a little bit, to see what the MRI has to say and go from there."
Later on in the article we do find out that Bourgeois did fly back to Round Rock to join the team, but I'm guessing he'll be coming right back.
