Jeremy Lin's agent said his client and the New York Knicks may part ways this summer, opening the hairy prospect of Linsanity's early demise in the Big Apple.

The star point guard becomes a restricted free agent on July 1, which leaves him the option to explore contracts with other teams but gives the Knicks the right to make a final offer matching any other bid.

Lin's return was assumed a foregone conclusion, but his agent, Roger Montgomery, said there are no guarantees.

I don't expect that. We're not anticipating that's going to happen, he told the New York Post. We don't have assurances of anything. I know history shows most restricted free agents go back to their team, but I'm not going to assume anything. We're waiting to see what happens.''

Montgomery's remarks come after Lin said on the final day of the season that nothing is set in stone,  throwing the prospect of seeing No. 17 in Madison Square Garden up in the air.

It's up to Lin and his agent to find a franchise willing to outspend the Knicks, who can match any offer. Lin made $762,000 last season.

Lin became a sensation in New York last season after coming off the bench to lead the Knicks to seven straight wins, eventually becoming a regular starter. The emergence of Linsanity also created a financial boon for the franchise, which saw global merchandise sales skyrocket. His season ended on April 2, when he underwent surgery to repair a torn meniscus in his left knee.

Given the obvious return on investment Lin offers, several reports claim the point guard will be back next season.
