Authorities assisted Denard Robinson and a female passenger early Sunday after the Jaguars running back drove a Chevrolet Impala into a retention pond on Jacksonville's Southside, according to a Sheriff's Office crash report.

Robinson, 25, was asleep at the wheel when an officer responded, but authorities determined he was not impaired and should not face a DUI charge, according to the report.

The responding officer arrived at the pond near Beach and Southside boulevards about 4:20 a.m. after the crash was reported and noticed both people inside appeared to be asleep, according to the report.

The driver's side of the car was submerged in the pond, so the officer approached the passenger side and knocked on the window to wake the two up, according to the report.

The report said Robinson then "opened his eyes and then went back to sleep."

The officer continued to knock on the window until the passenger, 29-year-old Marissa O. Staples of Cincinnati, said "what's up," according to the report.

The officer explained the car was in a pond and they needed to get out.

Staples attempted to roll the window back up but the officer was able to reach in and unlock the door, according to the report.

Staples had to be pulled from the car because she refused to exit, according to the report, and Robinson was asleep the whole time.

After removing the passenger, the officer was able to wake up Robinson, turn off the car and remove his seat belt, according to the report.

Robinson thought he was still on the road and didn't want to exit the vehicle, according to the report. He tried to open the driver's side door about three times after the officer repeated that the car was sinking in the pond, according to the report.

The door was submerged and Robinson eventually got out of the vehicle through the passenger's side, according to the report.

Neither person was injured, and they refused assistance from rescue workers, according to the report.

Investigators determined Robinson was westbound on Beach when he tried to turn onto Southside and drove over a sidewalk and into the pond.

A second officer screened Robinson at the scene for possible impairment but determined he was not, according to the report. The report did not indicate how he came to that conclusion or what tests if any were done. No citations were issued.

"The team is aware that running back Denard Robinson was involved in a single-car accident over the weekend and is thankful that nobody was injured," the Jaguars said in a statement Tuesday.

It was unclear where Robinson was heading or came from, but he said he realizes he shouldn't have been driving tired at that hour.

"I just wanted to let everyone know that I was involved in a single-car accident on Saturday night, and thankfully, everyone was safe and remained unharmed," Robinson said Tuesday on Twitter.

"I thank God every single day for the opportunities he has presented me with and I'm grateful every morning to wake up healthy.

"I should not have been driving that late or when I was that tired, but again, I'm just glad that everyone was safe. God Bless," the statement said.

Robinson will enter training camp in a battle for the third spot on the depth chart behind Chris Ivory and T.J. Yeldon. Robinson has rushed for 914 yards with five touchdowns in his three seasons with the Jaguars combined. He was selected in the fifth round of the 2013 draft out of Michigan and converted from quarterback and is entering the final year of his contract.
