Martin has been in contact with the Scarlet Knights coaching staff since Sunday and has assurances that Flood plans to honor his scholarship offer.
"Yeah, Rutgers is behind me all the way," Martin said. "They're supporting me."
Martin said he also heard from associate head coach Norries Wilson and other members of the coaching staff involved in his recruitment.
"They all reached out to me," Martin said. "[They said] hang in there and get better."
Martin spent the week on a walking brace, but said he did not have any major movement problems. X-rays after the injury came up negative, but Martin has yet to receive his MRI to determine ligament damage.
Recovery time or surgery for Martin's injury cannot be determined until the MRI results, but severe ligament tears could have him out of action for 12 months.
Martin is the 41st rated running back in the class of 2014 and chose the Scarlet Knights over finalists West Virginia and Pittsburgh. He joins Palmetto (Fla.) back Josh Hicks and Jersey City (N.J.) St. Peter's Prep back Jonathan Hilliman in the Rutgers recruiting class.
UPDATE, 8:20 p.m. -- Doctors told Martin he should not expect news until Friday at the earliest.
