Help ID this episode or tv film 1970s
Hi all,
I've been trying to ID the following film/episode I saw during the mid to late 1970s on TV, it featured an American football player who loses his arm in an auto accident, he receives a replacement from a recently executed psycho killer, but the arm/hand takes on the killer's past ways, which results in the innocent guy attempting to strangle his girlfriend/wife while he sleeps on the sofa.
Any help finding this, would be appreciated.
