The genre called "southern rock" doesn't really include SRV, per se, since there wasn't much country or rockabilly influence in his music. Early ZZ Top qualifies, but the later stuff not so much.
Stretching it a bit, the connections go all the way from Carl Perkins and Elvis and Johnny Cash to Buffalo Springfield and the Byrds to Lowell George and Little Feat to The Flying Burrito Brothers and Poco and the Eagles. John Hartford played on Sweethearts of the Rodeo, then created the seminal newgrass album Aerioplane. Members of the Eagles were briefly Linda Ronstadt's back-up band. Jackson Browne co-wrote Take It Easy, and was briefly a member of The Nitty Gritty Dirt Band.
Other bands like Lovin' Spoonful, Creedence Clearwater Revival, and the Band, to name a few, incorporated a country sound into their rock sound. Hank Jr., Travis Tritt, Marty Stewart, David Allen Coe, and many others were more "country", but definitely were influenced by rock and country and blues.
So, while not strictly "southern Rock", the mixture of rock, blues, and country influenced southern rock and rock in general from the very earliest days...
