Tackling is becoming a thing of the past at the Carolina Panthers’ training camp in Spartanburg, S.C.

In an effort to avoid unnecessary injuries as a result of contact, Carolina — like many teams around the N.F.L. — is emphasizing form tackling during team drills, with defenders wrapping up ball carriers but not taking them down to the ground.

Panthers Coach Ron Rivera said that was a big change from when he played linebacker 25 years ago for the Chicago Bears. In those days, two-a-day practices and all-out tackling were the norm.

Rivera said the way teams now approach teaching tackling changed out of necessity.

Now, Rivera oversees practices in which players are yelled at by coaches if they take an offensive player to the ground, except during so-called live drills that are few and far between at training camp.
