C/call, C/call, shove to me suggest slowplaying or drawing and hitting.
I think the only hands he's limping with and then calling a raise with that include a 4 are A4 or pocket 4's and going of his play i think he had 4's.
Another possibility is he caught a set with maybe 5's but i think he would have raised at some point before the river if this was the case.
