Should I call at the river?

[3rdEye]

I only called at the river here because I thought it was possible that the guy had AK, but I was pretty sure it was an overpair. Was I right to call for the size of the pot? Obviously I'm not getting away from this hand at the turn, but I think the river call was poor.
