That crossover will likely never happen, according to Dave Erickson. According to Digital Spy, he said “the short answer is no” when asked about the possibility of a crossover.
Fear the Walking Dead is a prequel series to The Walking Dead. With the second season, the characters will barely reach the time that Rick woke up from his coma during the start of The Walking Dead.
Cliff Curtis from the new series did make a joke about his character meeting Rick Grimes. He said:
“Travis a very jealous man. I think Rick Grimes might seem very attractive to [Travis’s wife] Madison… and I’d have to kill him!”
