Tosefta על דברים 16:6

All sacrificial animals that are sacrificed before the morning Tamid or that are delayed after the afternoon Tamid -- behold, they are disqualified, as only the incense may be [offered up] before the morning Tamid, and only the incense may be delayed until after the afternoon Tamid and the Passover offering on Passover Eve and [the offerings brought by] those lacking atonement, in order that [with respect the Passover offering], they may partake of the Paschal lamb in the evening (see Deut. 16:6). Rabbi Yishmael bar Rabbi Yochanan ben Berokah says, those who lack atonement bring their sacrifices along with the afternoon Tamid, in order that they may partake of consecrated [foods] in the evening.
