Howie Roseman apparently needs some pass-catching pointers from A.J. Brown ... 'cause the Eagles exec just sustained a facial injury out at Philadelphia's Super Bowl parade following a failed beer can toss.
Check out some photos of the Philly general manager on Friday ... he's walking the parade route with a big ole gash on his forehead -- after he reportedly failed to snag a flying alcohol container from a fan.
Thankfully, while the wound looks gnarly, Roseman's remained in great spirits.
