The way Steve Nash sees it, if the next time he suits up for the Los Angeles Lakers goes south because of the chronic nerve issues in his back and hamstrings, it could be the last basketball he plays in his illustrious 18-year career.

With that in mind, Nash is making sure he does as much as possible to get his body right before making what could be his final comeback attempt as an NBA player.

"At some point, I have to also realize, do the safest thing, the best possible opportunity to play basketball again rather than letting my angst get the better of me and jumping back in there," Nash said after the Lakers' shootaround Friday. "I know I can get healthy. It's a matter of, 'Can I sustain it?' And I'm just trying to get that health under my belt for an amount of time where we feel confident that it can be sustainable is the tricky part, and that's probably going to take a little while longer than I was hoping."

Nash, the league's oldest player -- turning 40 next month -- originally hoped to return to the lineup sometime during the Lakers' upcoming seven-game Grammys road trip Jan. 15-26, but he has since decided to use that time to go back to Vancouver, British Columbia, for the fourth time this season to undergo rehab with personal trainer Rick Celebrini.

If all goes well, Nash will practice with the Lakers for a week when they return from their extended road trip and attempt a comeback during the first week of February with about 35 games left in the regular season.

"It's all super speculative at this point because it's such a weird, tricky dimension when you're talking about this nerve issue," Nash said.

Nash exited at halftime of the Lakers' loss to the Minnesota Timberwolves on Nov. 10 and has not played since. He is averaging 6.7 points and 4.8 assists per game this season while shooting 26.1 percent from the field. He has two years remaining on his contract with the Lakers, set to pay him $9.4 million this season and $9.7 million in 2014-15.

Nash said that the time away from the team -- missing the past 24 games -- is starting to wear on him.

"That just eats away at me every day -- how far away I am from the game," Nash said. "It's been almost two months now. It takes a while to get your rhythm and everything down. So the anxiety and stress over the last eight months have been very unwelcomed."

After his last trip to Vancouver in early December, Nash was able to participate in three straight days of Lakers practices without a setback. However, two days after the string of consecutive work, discomfort set in.
