EXCLUSIVE

USC cornerback Josh Shaw -- who got busted lying about being a hero -- is back from suspension, but some of his Trojan teammates tell TMZ Sports they're not happy he's putting on the pads again.

Shaw was reinstated by the team Tuesday after he was suspended back in September for concocting a fake story about saving a drowning child to cover up how he injured himself.

We spoke to several Trojans who say they were "speechless" when they heard Shaw was rejoining the team -- because they don't think he deserves to start over players who didn't get in trouble and have been playing all season.

The team has 2 big games left this season -- UCLA and Notre Dame -- and although Shaw is not yet listed as a starter, many players think it's only a matter of time.
