Per the Terrion Arnold page in the wiki, his attorney has confirmed that three NFL teams have contacted him about employment since the Lions released him (following his arrest on four counts of kidnapping and four counts of armed robbery).
However, the specific team names aren't named in any of the sources — the attorney's statement didn't disclose which clubs reached out. So we know the number (3) and that Arnold expects to be signed by another team within 30 days (per a motion his attorney filed), but we don't know exactly who's in the mix yet.
