The High School Musical heartthrob had his jaw wired shut and required stitches after slipping in a puddle outside his Los Angeles home at the start of November.
But showing he's definitely on the mend, the gorgeous star uploaded a picture to WhoSay and Instagram on Sunday (15 December) showing himself beaming after watching the Indiana Colts beat the Houston Texans.
Zac, 26, was seen posing alongside Colts owner and CEO Jim Irsay. He added the caption: "Thank you Jim for a truly memorable trip to Indie - congrats on the win, @Colts!"
We're glad the smile is back!
Next up for Zac is bromance comedy That Awkward Moment, which revolves around three guys who love their party-packed single lives but when romance arrives on the scene it all becomes, you guessed it, a bit awkward.
Meanwhile, he's sent his support to his High School Musical castmates on the news they are reuniting for charity, although he is unable to join them.
Vanessa Hudgens, Ashley Tisdale, Corbin Bleu, Lucas Grabeel, Kaycee Stroh and Olesya Rulina will regroup at a charity fundraiser in Los Angeles this month which has been organised by Monique Coleman (who played Taylor McKessie) and her GimmeMo' Foundation.
Zac tweeted after the announcement: "Thanks for organising the #HSMreunion @gimmemotalk! Sorry I can't be there, but I support your cause. Proud of you Mo!"
