Alabama star QB Tua Tagovailoa was hittin' them high notes -- singin' Marvin Gaye in his hospital bed Sunday night -- a day after enduring a super serious and painful hip injury.
Maybe it's the meds.
Tua suffered a dislocated and fractured right hip Saturday late in the 2nd quarter after two Mississippi State defenders fell on top of him ... leaving him bloodied and in crazy pain on the field.
The Heisman Trophy candidate -- and projected Top 10 pick -- was rushed to the hospital Saturday afternoon .
