Shane McMahon is back in the gym just weeks after tearing his quad at WrestleMania 39 ... and the WWE talent was in great company -- 'cause he was sweatin' it out with All-Pro Tennessee Titans running back Derrick Henry!!
Shane -- donning a large brace on his left leg -- posted video of his workout on Tuesday ... showing him going through a series of exercises as he attacks his rehab.
The two were accompanied by famous athletic trainer Melvin Sanders -- who works with all the biggest names in the NFL -- as well as Luke Miller, who is Dak Prescott and Zeke Elliott's physical therapist.
Snoop Dogg Pins The Miz At WrestleMania
Remember, Shane-O-Mac -- who hadn't appeared on WWE programming since the 2022 Royal Rumble -- came out during a segment featuring The Miz and Snoop Dogg at WrestleMania at SoFi Stadium.
Snoop set up an impromptu match between Shane and The Miz ... but it was called off after McMahon tore his quadriceps.
53-year-old McMahon suffered the injury after his knee buckled following a leapfrog -- but thankfully, WWE's medical team was able to intervene swiftly.
Snoop Dogg ended up saving the day -- he fought Miz in place of Shane ... and defeated the former WWE champion using The Rock's signature "People's Elbow" finisher.
