Tv bosses behind Tracy Morgan's upcoming comedy series have vowed to put the project on hold until the actor is well enough to return to work after an horrific car crash left him in a critical condition.

The former 30 Rock star remains in intensive care after the limo bus he was travelling in on Saturday (07Jun14) was rear-ended by a truck, killing his comedy writer friend James 'Jimmy MACk' MCNair, and leaving four others, including Morgan, injured.

Morgan had been due to begin shooting the as-yet-untitled scripted series for America's Fxx network in August (14), but he is now facing a long recovery period as he continues to receive treatment for a number of ailments, including a broken leg, a broken nose and several broken ribs.

Producers have now issued a statement pledging their support to Morgan.

The press release reads: "The only thing we are concerned with is the health and recovery of Tracy Morgan and the victims of this tragic accident.

"We will support Tracy and his family in every way possible throughout his recovery. At the point when Tracy has recovered and decides that he is ready to go back to work, his show will be waiting for him. Right now our thoughts and prayers remain with Tracy, the other victims of the accident, and their families."

The new show has been written by It's Always Sunny in Philadelphia stars Rob MCElhenney, Charlie Day and Glenn Howerton.

Truck driver Kevin Roper has since been charged with one count of death by auto and four of assault by auto. Prosecutors claim Roper, a driver for U.S. superstore Wal-Mart, had not slept in more than 24 hours prior to the fatal accident.
