Jon Rahm believes the American can compete, and even win tournaments after returning from injury at Augusta.
Woods was in hospital for three months and nearly had his leg amputated following his car crash in 2021. The former world number one was going almost twice the legal speed limit and hit a tree at around 75mph.
The 15-time major winner somehow took place at the PNC Championship alongside his son Charlie in December before making his competitive return last Thursday. It was his first appearance at a top level event since the 2020 Masters in November.
Woods defied the odds to card an opening 71 at Augusta National before struggling in the next few rounds, including back-to-back rounds of 78 which were the highest scores of his career at the Masters.
Rahm played alongside Woods in the final round and the world number three said: "It's really cool. It was great because nobody cared about me, so I was just watching him play.
"I was one more spectator, and I ended up playing good (shooting 69). It was kind of a load off my shoulders in that sense. I was able to enjoy it as a fan and as a player."
Woods said that the injuries he suffered to his right leg in the accident were so severe that amputation was "on the table" at one point.
"You can just tell that his leg is just not quite up there yet," Rahm added.
"I've seen him in the (physio) truck. He is limping in the truck. He is limping on the course. Obviously, he is trying very hard to play, but it's not easy to walk up and down those hills.
"At the end you can just tell that his leg and his body are just not used to walking this much, right?
"I believe if at home he can walk and get strength up and stamina in that sense, he will be able to be competitive again. This is the hardest walk all year. He will be able to go somewhere where it's a little easier to walk. It won't be as long, and I believe he'll be able to contend."
