Tracy Morgan is expected to return to the set of "30 Rock" Tuesday after collapsing during the Sundance Film Festival last weekend.

The comedian had just received an award from the Creative Coalition when he became ill. Morgan's publicist, Lewis Kay, said Monday that Morgan was suffering from exhaustion and that Park City, UT's 7,000 ft. altitude contributed to the comedian's collapse.

Morgan later tweeted that the high altitude "shook up this kid from Brooklyn," adding, "Superman ran into a little kryptonite."
