The Chiefs haven't touched on the subject much other than to say it was non-life threatening.
Weis hadn't attended a practice this week until he made an appearance this morning, Kent Babb of the Kansas City Star reports.
He's back on the motorized cart like you saw in training camp but it's good to hear that he's returned.
Early reports suggested he wouldn't miss any games because of the surgery and it appears that'll be the case.
