5 wrestlers who might come out of retirement and five who are done for good

Might Return: Jack Swagger

The All American American asked for—and received—his release from WWE in 2017. His goal was not to pursue a career in another wrestling federation, but to make the jump to MMA and increase his wrestling stock, a-la Brock Lesnar or Bobby Lashley.

Swagger has a good chance of backing up his, er, swagger, as he is a champion amateur wrestler and has incredible reach and balance. If he does well in Bellator, he may be able to return to the WWE at or near the top of the card.
